HARVEY OLSEN, OF NEW YORK, N. Y., ASSIGNOR TO MICHAEL J. CAFIERO, OF KINGS COUNTY, NEW YORK.

CABLE HOLDER.

Application filed April 2,

To all whom it may concern Be it known that I, HARVEY OLSEN, a citizen of the United States, and resident of New York, in the county of Bronx and State of New York, have invented certam new and useful Improvements in Cable Holders, of which the following is a specification. t

The invention relates to improvements in cable-holders designed particularly for supportinga vertical line of one or more electrlc 'cables or conductors arranged within a conduit pipe or casing,'the holders being provided at suitable points along the line to afford the necessary protection to the cables and a division of the weight thereof. One object of the present invention is to provide connection means for clamping the cable without abrasion or injury and for transmitting its weight to the casing. A further object is to provide means for detachably connecting the holder for renewal without the removal of the casing or the conductors, and for permitting the addition or removal of cables inthe line, Also, an object is to provide means for sealing the connection joints against the admission of water or moisture.

In describing the invention in detail, reference is had to the accompanying drawing, forming a part of this specification, and wherein like characters of reference are used to designate corresponding parts throughout the several views, andin which:

Figure 1 is a sectional elevation of the holder and casing shown in connection with a. single cable; Fig.2, a plan view of the same; Fig. 8, a sectional elevation of a holder arranged for two cables Fig. 4:, a plan View of the latter; Fig. 5, a sectional elevation of a holder arranged for three cables; and Fig. 6, a plan view of the latter holder.

In the drawing numerals 1 designate vertically' disposed conduits or casings,anchored in any approved manner to the side walls of a building and provided at their upper ends with bushings 2, arranged in connection with the several holders herein shown. As indicated in Figs. 1 and 2, for a single cable, the holder consists of a sectional socket comprising the two parts 3 and 4:, having a joint along the central line 5, and held together at their A Specification of Letters Patent. Patented J 11119 13, 1922.

upper ends by means of the annular band or strap .6, provided with the clamp-screw 7. At their lower ends the parts are reduced to form the shoulders Sand the socket-shank 9, the former being adapted to form seats WhlCh engage as a support the bushing 2, and the latter fitted within the 'pipe 1 and held thereby against spreading apart under load. Extending centrally through the shank section of the socket in alinement with the sectional joint line 5, corresponding with the normal axial line or run of the cable, is a cable-passage 10, which continues upwardly and angularly into the upper or body portion of the socket section 4 and forms therein a recess 11, having an outwardly flaring semi-circular wall constituting a clamping face 12. In the upper part of the opposite socket section 3, is a semi-cylindrical recess 13, enlarged with respect to the one in section at to form at the joint-walls of the latter the shoulders 14 adapted to be engaged by corresponding ledges formed on the wedge-block 15, the latter being provided with an angular clamp-face 16, conforming to and coacting with the opposite clampinv face 12. As thus constructed the sectional socket and the wedge-block are fixed against rotation with respect to each other to prevent lateral movement of the cable when the latter is clamped therebetween, the wedgeblockbeing slidably mounted in the recess 13 and engaging the cylindrical side walls of the latter under the pressure of its clamping action to hold the single cable 17, the weight thereof serving to increase such clamping force between the angular faces 12 and 16 which act to transmit the weight without slip to the casing 1.

The socketsections and the wedge-block may be formed of insulating material, preferably of hard wood, as maple, impregnated under heat with paraflin or other suitable moisture and weather proof material. The clamping faces of the parts are shown formed perfectly smooth to prevent any abrasive or are alined with the joints 5 of the sections, and a recess 19 is formed in the upper portions of the sections or socket by means of the outwardly flared wall 20, constituting angularly disposed clamping faces "for the cables 21. Disposed within the socket is a wedge-block 22, having opposite angular clamp faces 23, shaped to coact with the clamping faces 20 of the socket sections.

The three-cable holder, shown in Figs. 5 and 6, is provided with a socket having three similar sections 24, connected together on the joint line 5 along which the passages run for holding the cables 25. In like manner the two-cable holder, the upper portions of the socket sections form a recess 26, having outwardly flaring inner walls 27, constituting cable clamping faces out of line with the cable-passages in the shank portions of the socket. Also, the means, as shown, for securing the sections together at their upper and lower ends are common with that described for the one and two cable holders. The wedge-block 28 is provided with three angular clamp-faces similar to the clamp faces 16 and 23, which coact with the clamping faces 27.

The action of the wedge-blocks is common in the several holders to spread or throw the cable out of its normal vertical line and force it against the clamping face of the socket. Also, by means of the detachable band 6 the wedge-block and socket sections may readily be removed and replaced, allow ing cables to be added or taken from the line without disturbing the casing.

In order to protect the connection joints of the cables at the top of. the holders, the several recesses ll, 19 and 26 thereof are adapted to be filled with a water-proof compound of any approved quality. As shown in Fig. 5, the convex dotted line 30 indicates the top surface of the filling, the body of which within the recess is shown in dotted hatch lines.

WVhile only a single casing section and holder are shown in one line, it is to be understood that several sections or casings may be vertically arranged in spaced relation in a single line, in the usual manner, and a holder provided for connecting the cable or cables to the top oi each casing section, whereby the weight oi? any desired length of cable may be divided and supported at several points along its line to prevent excessive strain or scratch thereof.

lVhat I claim my invention and desire to secure by Letters Patent, is:

1. A cable-holder for a conduit pipe comprising a socket longitudinally divided into sections and arranged to be seated on the upper end oi the pipe, means for detachably securing said socket sections together, said socket being provided with a cable passage extending through its lower end, and at its upper end a recess having a flaring wall constituting a cable clamping seat disposed at an all le to the cable passage, and a wedgeblock disposed within the recess and arranged to clamp the cable against said angular seat.
